LF50CV

Overview

The LF50CV is a very low drop linear regulator from the LFXX series, manufactured by STMicroelectronics. It provides a fixed positive output voltage of 5 V with a maximum output current capability of 0.5 A. The device operates within an input voltage range of -0.5 V to 40 V and features a typical dropout voltage of 0.45 V. It is housed in a 3-pin TO-220AB package with a tab for thermal dissipation. The regulator maintains high output precision with a line regulation and load regulation of 25 mV each, and a voltage accuracy of ±2%. It functions reliably across a temperature range of -40 °C to +125 °C.

Feature Summary

Very low dropout voltage operation suitable for battery-powered systems
Low quiescent current consumption for power efficiency
Integrated thermal protection mechanisms

Applications

Battery powered systems
Low noise applications
Low power applications

Procurement Notes

Verify the specific datasheet version and package marking for the LF50CV to ensure compatibility with design requirements. Confirm that the TO-220AB package style meets the thermal and mechanical constraints of the target application. Cross-reference the manufacturer's official documentation for any updates regarding RoHS compliance or discontinuation status before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5 V supply is required with moderate current handling up to 0.5 A. The wide input voltage range allows flexibility in source selection. Ensure the application benefits from the low dropout characteristic and that the thermal performance of the TO-220AB package is adequate for the expected power dissipation levels under operating conditions.

Part Context

The LF50CV belongs to the LFXX family of very low drop regulators designed for low-noise and low-power environments. This series offers various output voltages and packages, emphasizing efficiency in battery-operated devices. The LF50CV specifically targets applications requiring stable 5 V regulation with minimal voltage loss between input and output.
